I know that protons and electrons do not actually spin, although they have the property of spin.
I was learning about MRI. I was introduced to the idea that you have the spin of the proton in the external magnetic field. Since they are not perfectly aligned, it will cause precession just like in a spin top. I understand how precession occurs in spin tops and bike wheels, but that's dependent on the object actually spinning and having the velocity to change.
If protons don't spin, do they actually precess too? I would imagine not, because that would imply that they're actually spinning. If not actually precessing, then what is this precession?
